If you're going to be shooting a LOT of heavy loads like Double Tap/Buffalo Bore, you might go up a couple pounds. If you're just going to sparsely shoot hot loads and mix in some plinking ammo, you'll be fine with the stock spring.

The stock recoil spring on all the Glocks is too light for my tastes. I use a 20# recoil spring on a captured ss guide rod on my G20, G22, and G23. The heavier slides on my G20L, G21L and G24 make up for the lighter recoil spring so I use the std one unless I'm shooting some hot or nuclear loads.

I've got one of each on your list and can't tell the difference between them.
